Description

Technical Field

[0001] The invention belongs to the field of desktop multifunctional electronic identity document recognition, in particular to a desktop multifunctional electronic identity document recognition machine. Background Art

[0002] An ID card recognition machine is a device that can determine whether an ID card is forged. Like a banknote detector, it can effectively identify the authenticity of an ID card. ID card recognition machines are currently divided into two recognition methods. One is the traditional reading through a card reader, and the other is to use a camera to take a photo of the ID card and then use OCR technology to recognize the text information in the image. Since camera recognition is more convenient and can be read normally even if the ID card is demagnetized, it has gradually replaced traditional card reader recognition.

[0003] Existing identity document recognition machines have the following disadvantages:

[0004] 1. Recognition accuracy is greatly affected by light source, which requires users to constantly adjust the angle when identifying their ID cards.

[0054] The specific workflow is as follows:

[0055] First, place the ID card from the ID card placement port 1009 onto the placement plate 2207. The limit blocks on the placement plate 2207 limit the two sides of the ID card. When the optical switch 2005 detects that the user's hand is inserted, the optical switch 2005 will start the cylinder 2201. The deep cylinder 2201 drives the floating joint 2202 and the placement plate 2207 to rise. The rising placement plate 2207 drives the ID card to rise, so that the ID card rises to the position of the groove 2311. Then start the second stepper motor 2301. The second stepper motor 2301 rotates to drive the first turntable 2306 to rotate. The rotation of the first turntable 2306 drives the connecting rods 2307 on both sides to swing. The two connecting rods 2307 swing through the two second protrusions 2308 to drive the two clamping plates 2303 to approach each other. The clamping plate 2303 drives the second turntable 2309 to clamp the ID card, and the ID card will enter the groove 2311 under the guidance of the guide port 2310, so that the second turntable 2309 can fix the ID card more stably, and then start the first stepper motor 2101. The rotation of the first stepper motor 2101 drives the spline shaft 2106 to rotate, and the rotation of the spline shaft 2106 drives the first synchronous wheel 2103 to rotate. The rotation of the first synchronous wheel 2103 drives the second synchronous wheel 2104 to rotate through the synchronous belt 2105. The second synchronous wheel 2104 rotates to drive the second turntable 2309 to rotate, and the rotation of the second turntable 2309 drives the ID card to rotate, so that the side of the ID card that needs to be identified is aligned with the second camera 2007, and then the fill light 2004 is started to make the fill light 2004 illuminate the side of the ID card that needs to be identified, and then the second camera 2007 is started to shoot. Since the light shield 1004 blocks the external light source, it prevents the halo and reflection generated during identification from affecting the identification of the second camera 2007, thereby improving the accuracy of identification.
